Iinqwelo zokusila ezishushuzibalulekile kwimveliso yoluhlu olubanzi lwesinyithi kunye ne-alloys kumashishini ahlukeneyo njengeemoto, i-aerospace kunye nokwakhiwa. Umgangatho wemveliso yokugqibela ixhomekeke kakhulu ekusebenzeni komsebenzi kunyeimiqulu yogcino isetyenziswe kwinkqubo eshushu yokuqengqeleka. Kule bhlog, siza kuxoxa ngokubaluleka kokusebenzisa imiqulu ekumgangatho ophezulu kwiindawo zokusila ezishushu.

Imiqulu yomsebenzi zizixhobo eziphambili ezisetyenziselwa ukukhubaza kunye nokubumba izinto eziqengqelekayo. Bahlala bephantsi kobushushu obuphezulu, uxinzelelo olugqithisileyo kunye nokungqubuzana ngexesha lenkqubo eshushu yokuqengqeleka. Ngoko ke, kubalulekile ukusebenzisa imiqulu ekumgangatho ophezulu eyenziwe ngezinto ezinokumelana nezi meko zinzima ngaphandle kokuchaphazela ukusebenza kwazo kunye nokuphila ixesha elide. Imiqulu yomsebenzi ekumgangatho ophezulu ayiqinisekisi kuphela ukwakheka kwezinto ezihambelanayo nezichanekileyo, zikwanciphisa umngcipheko wokungaphumeleli kwamanqaku kunye nexesha lokuphumla elineendleko.

I-backup rolls, ngakolunye uhlangothi, ixhasa i-work rolls kwaye inceda ukugcina imilo kunye nobukhulu bezinto eziqengqelekayo. Njengemiqulu yomsebenzi, i-backup rolls ibonakaliswe kumaqondo okushisa aphezulu kunye noxinzelelo, kwaye umgangatho wabo uba yinto ephambili ekusebenzeni kakuhle kunye nokuchaneka kwenkqubo eshushu. Ukusebenzisa ii-backup rolls ezikumgangatho ophezulu kuqinisekisa inkxaso efanelekileyo yee-rolls zomsebenzi, ukunciphisa ukuguqulwa kwezinto eziphathekayo, kunye negalelo ekuthembekeni okupheleleyo kunye nokuhambelana kwe-rolling mill.

Isishwankathelo, utyalo-mali kwii-rolls ezikumgangatho ophezulu, kubandakanywa umqulu womsebenzi kunye ne-backup rolls, kubaluleke kakhulu ekusebenzeni kakuhle kunye nokusebenza kakuhle kwe-hot rolling mill. Abavelisi kunye nabavelisi kufuneka babeke phambili umgangatho woluhlu kunye nokuqina ukuqinisekisa imveliso egqityiweyo ekumgangatho ophezulu. Ngokukhetha iiroli ezifanelekileyo kunye nokuzigcina ngokuchanekileyo, iinkampani zinokunciphisa ixesha lokuphumla, ukunciphisa iindleko zokugcina, kwaye ekugqibeleni zandise ukusebenza ngokubanzi kunye nemveliso yezixhobo zabo zokusila ezishushu.
